Maple Leaf Portal/tunnel boring news

Sometime today, Thursday, July 31, TBM Brenda will have chewed her way through 500 feet of Maple Leaf soil on her way south to Roosevelt Station. Another TBM now being assembled at the Maple Leaf Portal will start carving the southbound light rail tunnel sometime in October.

I’m guessing Brenda is a bit dirtier these days.

Roosevelt Station news

Station box wall construction now complete, the main work at the Roosevelt Station construction site is now the *excavation* of said station box. Crews are digging down about four feet at a time, removing soil from the station box area, pausing to stabilize the station walls that have been newly revealed, and then digging some more.

The station box needs to be fully excavated by the time Brenda arrives, sometime in early 2015.

And now for some NE 65th Street detour news:

In mid to late August, drivers heading past the Roosevelt Station site on NE 65th Street during the day may be detoured due to a project to install water lines under the road at the intersection of NE 65th Street and 12th Avenue NE. The signed detours will be in place from 7 a.m. to 3 p.m. weekdays. Westbound drivers can expect detours via 12th Avenue NE, NE 70th Street and Roosevelt Way NE and eastbound drivers can expect detours via 12th Avenue NE, NE 75th Street and 15th Avenue NE. Only one direction of travel will be detoured at a time.

These detours combined with the work on the Rooster Apartments on the west side of Roosevelt Way NE are making travel on NE 65th Street through the Roosevelt neighborhood a pain for all concerned (drivers, pedestrians, cyclists, etc.). We urge all travelers in the area to have some patience and practice grace-filled egress in the area.

U District Station News

This week, crews are digging holes in which to place piles that will make up the southern wall of the station: 76 holes, each between 50 to 105 feet deep. To help speed this work along, crews are now on site on Saturdays AND using two drill rigs.

NE 43rd Street east of Brooklyn Avenue NE is still closed to motorists, but what are you doing driving around in that area anyway it is a mess.

Northgate Link webcams

If you’re sitting near internet and wondering how construction is doing at any of the above locations, there’s a webcam (or three) for that:

Each page also has a “Stream Time-Lapse Movie” button on the left-hand side, for those who appreciate more action than a live shot once every 15 minutes.

UPDATE (2:17 PM): Just into the Ravenna Blog inbox is a Roosevelt Station construction alert for Saturday.

Saturday morning concrete pour at Roosevelt Station construction site

On Saturday, Aug. 2, construction crews working for Sound Transit will begin work at 7 a.m. for a concrete pour. Residents may notice noise from truck engines.

Crews will do everything within reason to keep noise to a minimum.

Why is this concrete pour happening on Saturday?

High demand for concrete resulted in limited schedule availability for the concrete pour at Roosevelt Station. Doing the work on Saturday morning will help keep the project on schedule by at least two weeks.

The TBM’s 21-foot-diameter cutter head (the large green and yellow disc on the front of the TBM) is covered with teeth and holes, turns at a rate of 0.1 to 2.5 revolutions per minute, and can excavate an average of 40 feet of tunnel per day.

It’s also great for posing with.

View inside the cutter head. Here the tailings that have passed through the openings in the cutter head will fall, be carried out by this red screw conveyor, and moved through the body of the TBM.

This is the “trailing gear” that follows behind the TBM. It carries equipment for the boring machine and helps carry the spoils away from the machine. Altogether, the TBM and the trailing gear stretch out to the length of a football field.

As the TBM and the trailing gear carve the route to Roosevelt and beyond, supply trains will ferry equipment from the outside world down into the tunnels. Chief among their cargo will be the pre-cast concrete segments that compose the finished walls of the tunnel as well as provide a surface for the TBM to propel herself forward.

Good news for those living and working (and attending the UW) above the Northgate Link Extension tunnels: Vehicles equipped with rubber tires will be used this time around for underground deliveries.

Worm’s perspective of the cutter head.

Sound Transit has a great little video showing how tunnel boring machines work. It includes a cross-section graphic of the machine in action, as well as footage from previous excavations.

…

And here’s where we pause the photo essay to share with the Roosevelt neighborhood some potentially great news.

The old plan for tunneling south was for Brenda to dig one side of the route to Roosevelt Station, be trucked back up to the Maple Leaf Portal, and begin digging the other side of the route. Then a second TBM-to-be-named-later would join her in Roosevelt, where the pair would start their journey south to the University of Washington Station. Muck from the tunneling would travel up to the Maple Leaf Portal site and be hauled away there for Brenda’s solo drilling, but would be hauled out of Roosevelt Station for the remainder of the project.

Sound Transit’s Bruce Gray tells me that this may no longer be the case. Via email:

In the new plan the Contractor has proposed two TBMs going from Maple Leaf. The performance of the tunneling and the muck haulage will be closely monitored during the initial drive from Maple Leaf to Roosevelt. If all goes well, the two machines will continue on to UW with spoils removal and haulage continuing from Maple Leaf the entire time. If the new proposal does not perform as planned there could still be muck haulage and/or a third TBM launched from Roosevelt in order to meet the project schedule.

What this would mean for the Roosevelt neighborhood is that after the dump trucks bearing away the soil from the station excavation are gone, they’d be GONE. Muck from the entire Northgate Link Extension would come out the Maple Leaf Portal and be hauled away there.

Again, this new plan is not a given. And it’s going to be a while before anyone knows the contractor’s final decision. Once Brenda gets digging in June, it will take her 10-12 months to reach Roosevelt Station (via Sound Transit’s Gray). If the second TBM launches from the Maple Leaf Portal five months later in October, the pair won’t see each other in Roosevelt until August 2015 at the earliest.

To be continued…

Hey, Roosevelt: Remember when you rallied to bring light rail closer to the neighborhood’s core at 12th Avenue NE (over a station closer to I-5 on 8th Avenue NE)? On January 27, 2005, the Sound Transit board agreed with you, and the Roosevelt Station Alignment was chosen. Here, some stickers from that campaign pose with the machine that’s making it a reality.

A fragile bottle of dedicatory Washington apple cider sits in the shade along with TBM-signing Sharpies and commemorative pins.

The assembled crowd listens to officials during the dedication.

Sound Transit Board Member and City of Everett Councilmember Paul Roberts, and 46th District Representative Jessyn Ferrell, share a laugh during the dedication speeches.

Councilmember Roberts anoints the cutter head with a refreshing non-alcoholic beverage.

Then the signing began. Gathered participants were encouraged to write on the machine.

Blessed with some clear skies and lovely spring sunlight, we set out on Friday, March 21 to take some photos of the two Northgate Link sites seeing the most action right now: The Maple Leaf Portal and Roosevelt Station construction sites.

We’ve done our best to explain each scene and the work being done to the best of our knowledge. We will, of course, add additional information for more expert sources if possible.

Each of the photos below can be enlarged with a click of the mouse (or tap of the finger, mobile users).

Maple Leaf Portal

View from the NW corner of NE 92nd Street and 1st Avenue NE, looking north through the length of the Maple Leaf Portal (MLP) construction site.

View east from the same corner. Double dump truck headed to I-5 up NE 92nd Street.

Zoom from the same location. Sound Transit recently set up webcams at the active Northgate Link construction sites. The camera surveying the scene at the MLP can be seen on the far left side of the photo above. To see what’s happening from the camera’s viewpoint, visit this here EarthCam page.

View from the NE 92nd Street overpass of northbound I-5 drivers all wishing they could be riding a train instead of driving. Another double dump truck headed out with muck from either the MLP or Roosevelt Station sites is traveling with them.

On 1st Avenue NE now. No construction wall here to obscure one’s view of all the equipment and work being done. Looking south a bit here at the TBM.

Looking north at a very large excavator depositing soil into a double dump truck.

Close up of the TBM’s teeth, catching the spring sunlight.

View of the whole cutter head of the TBM, with a worker conveniently seated on the ground nearby for scale.

One of the pleasant side effects of doing reporting with a toddler around is that sometimes the construction folks wave and/or make faces. Thanks, guys.

Should you have any of your own small children or other construction vehicle fanatics in your circle of friends, there is a lovely viewing point on 1st Avenue NE at NE 95th Street which includes a cement wall perfect for sitting on. Perhaps with a sack lunch. Or a froyo.

Another nice side effect of carrying a cute kid around and using a big zoom lens is that people walking by say HI and ask what you’re doing. And sometimes these people are nice and understanding, and help you get even better pictures from their four floor apartment building. (Thanks, Tom!)

This is looking southwest at the “head wall” of the Maple Leaf Portal. You can see the NE 92nd Street overpass in the background. This head wall is where the TBM will begin its journey down to…

Roosevelt Station

Red crane “rabbit ears” behind the Dwell Apartments. This shot is taken from the parking lot of Roosevelt Square, looking north. We’ve been able to spot these red cranes from all over Northeast Seattle.

This is a large hydromill, used to dig the 130-feet-deep-plus slots into which the rebar cages are later lowered. Then cement is pored in, creating the “slurry walls” that make up the outer walls of the underground station. The walls of the station are built underground BEFORE excavation happens!

One of the rebar cages in some state of assembly.

Unlike the Maple Leaf Portal site, the Roosevelt Station area has many thick and tall construction walls up already. This is great for local residents — part of the construction mitigation which lessens noise and reduces dust — but not so great for taking pictures. Looks good, though. A Roosevelt High School-inspired green.

Construction-related vehicles have two entrances/exits at the Roosevelt Station site: One on 12th Avenue NE, and the other on Roosevelt Way NE. Above is a large truck backing out of the Roosevelt Way NE side with the help of a flagger.

A little local flair/signage on the site’s chain link fence. This temporary fencing along 12th Avenue NE will be replaced by more thick, green construction wall in the future.

Excavation work being done at what will be the southern entrance to the finished light rail station, on the NW corner of NE 65th Street and 12th Avenue NE. The piles of soil were steaming in the cool spring sunshiny air (though we suspect that part of this is due to heated water used in the excavation process — looking into it).

Another, smaller hydromill, working in the NE corner of the construction site (near where the northern station entrance will be located). Here, the jaws just emptied a load of soil into a mostly hidden dump truck.

Close-up, post dump. Look at those chompers!

Lots of cement trucks on this day. They were queued up three or four deep, waiting to their turn to pour.

All vehicles leaving the site get a wheel washdown, another piece of the construction mitigation package.

Close up after the pour was finished.

Happy little cloud.

Cozy bit of sidewalk along the east side of 12th Avenue NE. The cement wall on the right side is the west side of the Roosevelt High School track and field.

Another part of the construction mine field that is now the Roosevelt neighborhood is a new 42-inch sewer main under 12th Avenue NE. You know those metal plates you drive over? This shot shows you how deep the hole goes underneath your tire.

More steamy soil, moving out.

Close-up of steamy soil. (It looked really neat in real life, as the clouds of steam were carried away by the breeze. Trust me.)

The NW corner of NE 65th Street and 12th Avenue NE. Decidedly closed sidewalk, but that doesn’t always stop Roosevelt High School students trying to cross the street at open campus lunchtime.

An empty double dump truck headed up 12th Avenue NE, ready to fill up with another load of excavated soil.

Two pet mix-ups to share with you from over the past weekend. Please keep your eyes and ears open!

Lost Cat

Please Help Taz get back home. He was last seen on Tuesday, July 3, near Ravenna Ave NE and NE 70th St.

Taz is a neutered male cat with medium length black fur. He’s almost a year old, and a little smaller than average. He’s an indoor cat, and normally shy around strangers.

Please call, text, and/or email if you have seen him. Phone number is 406-4111, and the email address is LostRavennaCat@hotmail.com.

Found Dog

UPDATE (12:42 PM): Dog finder Vanessa tells us that the dog was chipped and the owner has been located!

This guy was found a little further out than Ravenna, but lost animals do wonder about.

This darling medium-sized, neutered, male dog was found the evening of 7/7/13 without any collar on Corliss Ave. N off of 92nd St. (The red harness pictured is a loaner.) He’s mostly black, with tan and white on his chest, legs, and feet. He was spotted on the loose in the same area a couple of weeks back (also collarless that time) but was not able to be apprehended — too fearful, shy, and skittish. Was won over with food and treats this time, and is an incredibly wonderful and loving guy, adapting readily to being around kind adults, kids, and another well-socialized dog. Will be taking him to vet shortly to verify whether he’s chipped. Please be in touch if you think you might know this dog and/or the owner — thank you! Contact info: rutabaga.unicycle@gmail.com.

Dog found on Sunday, July 7, on Corliss Ave N off of NE 92nd St. Was also seen roaming in same area in late June.

There are currently nine Patty’s Eggnest locations in Washington State, all of which are independently owned and operated. Patty’s specializes in breakfast. So much so that their Eggs Benedict have their OWN MENU. NINE different kinds, people.

We serve delicious, hearty meals made to order and made from scratch with fresh, choice ingredients. In a comfortable, family-friendly atmosphere, we’ll be happy to fill your table with home-cooked breakfast favorites. Fresh-squeezed orange juice, Swedish pancakes, scrumptious scrambles, and hearty chicken-fried steak are just some of the dishes that we feature on our menu at all locations. We also feature tasty lunches, like hot delicious sandwiches, big burgers with seasoned fries, and fresh salads. For several of our locations, we are open for dinner hours as well, serving fresh roasted turkey dinners and soup made-from-scratch.

That same Eater piece claims that “a Joey’s and a Din Tai Fung will also be moving in.” That’s a lot of restaurants. But with 24,626 sq. ft. of restaurant space available in that new building, anything is possible.

Over in the Laurelhurst direction, Bill the Butcher is getting a new, unlikely neighbor:

Another one for the TO BE CONTINUED pile. We’ll contact Cloud City and Seattle Parks and Recreation on this one and report back.

UPDATE (5:35 PM): We’ve heard back from one of the Sand Point Tennis Center managers, Scott Marshall, who said, “Cloud City will be the cafe operator inside of our 6-court building. We are extremely excited about this partnership.”

Ravenna and Roosevelt neighbors near the Roosevelt Reservoir were told (via mail, around Saturday, April 6), that not only was the reservoir disconnected from the city’s water system on Monday, April 1, it will soon be drained…and stay that way, for two years.

Roosevelt Reservoir, by neighbor Jenifer Gonzales.

The clock started ticking for all of the city’s open reservoirs back in the mid-1990s with the passage of an amendment to the Safe Drinking Water Act (SDWA). This amendment “added new requirements related to annual water quality reports, operator certification requirements, system capacity, and source water assessment and protection.”

Then, in 2006, a federal law “required all uncovered drinking water distribution reservoirs to either be covered or treated to a high standard.”

Of the city’s open reservoirs, six have now been replaced with underground structures: Magnolia in 1995, Lincoln in 2004, Myrtle in 2008, Beacon in 2009, West Seattle in 2010, and Maple Leaf in 2012. All but the Magnolia site were transformed into parks by various Seattle Parks and Recreation levy funds.

There are four above-ground reservoirs remaining: The Bitter Lake, Lake Forest Park, Volunteer, and Roosevelt Reservoirs.

Volunteer Park Reservoir in 2008, by Flickr user stevevoght.

Floating covers have been installed at the Bitter Lake and Lake Forest Park facilities, and will remain through the operational life of these two reservoirs.

To perform the tests, the reservoirs were taken out of service on April 1, 2013. While out of service, Roosevelt Reservoir will be kept drained, while Volunteer Reservoir will remain full with water and continue to be a water feature at the park.

The reservoirs will remain disconnected from the City’s drinking water system throughout the two-year test. During this time, SPU will study the impact the out-of-service facilities have on Seattle’s overall drinking water system, make evaluations and determine whether the reservoirs can be permanently taken out of service.

If SPU finds that the reservoirs are no longer needed, the costs saved by not having to replace them with covered storage facilities would run between $10 and $50 million dollars. Each.

If and when SPU decides the Roosevelt and/or Volunteer Reservoirs ares no longer needed, public process would then kick in, and neighbors would have a say in their futures.

Until then, enjoy a nice, tall glass of (c0vered) Maple Leaf Reservoir water, now flowing out of our taps.

UPDATE (Thursday, April 18): At least one neighbor of the Roosevelt Reservior has asked SPU “Why us?” And here is the reply by Bill Wells, Senior Engineer of the Drinking Water Division:

We had to make a difficult decision in weighing the benefits of keeping Roosevelt Reservoir full versus the additional costs to the customers of Seattle. We estimated that it would cost an additional $100,000 each year (about $200,000 in total) to keep the reservoir full during the two-year decommissioning test.

The costs to keep Roosevelt filled and maintained are significantly more than that of Volunteer. This is because Roosevelt Reservoir is a 50-million-gallon reservoir – more than twice the size of the 20-million-gallon Volunteer Reservoir.

Another key factor in the decision to refill Volunteer Reservoir is the park’s historical landmark status, of which the reservoir is a contributing feature.

We wish we could maintain water in both reservoirs throughout the two-year test period, but in the end we decided it was in the best interest of the city as a whole to keep Roosevelt Reservoir empty throughout the testing period.

Seattle City Light crews were responding to a power outage Tuesday that affected about 3,600 homes and businesses in the Ravenna, Roosevelt, View Ridge and Wedgwood neighborhoods of northeast Seattle.

The outage started about 11:20 a.m. A cause was not immediately known. An initial estimate for restoration of service was set for 3 p.m.

The general boundaries of the outage were NE 94th Street on the north, NE 65th Street on the south, Roosevelt Way NE on the west and Lake Washington on the east.

As of this posting, the cause is listed as “tree,” and the restoration time is estimated at 3:00 PM.

As we were calling the North Precinct about the dangerous traffic conditions at 15th Ave NE and NE 75th St — signals are out and many drivers on NE 75th St are not noticing and treating as a four-way stop — the officer on the other end of the phone blamed the outage on two transformers lost from the tops of poles, but we haven’t had confirmation of the exact cause from Seattle City Light.
